Abstract

The invention provides an ecological factorial breeding method of coilia ectenes parent fish. The ecological factorial breeding method of the coilia ectenes parent fish comprises the following steps: 1) an ecological spawning pond is built; 2) parent fish is selected; 3) the ecological spawning pond is processed; 4) the ecological spawning pond is managed; 5) the breeding is managed. The ecological factorial breeding method of the coilia ectenes parent fish artificially simulates a Yangtze River coilia ectenes breeding migration rule, the parent is provided with an ecological factorial breeding migration environment, by artificially controlling the external conditions of water flow, water temperature, illumination intensity and a period, osmotic pressure and the like, the fresh food intensity is strengthened, the parent is enabled to develop from body maturity to sexual maturity, parent fish can be kept every year, and the sustainable development of coilia ectenes ecological factorial breeding is achieved.

Description

technical field

[0001] The invention relates to an ecological factory breeding method for saury broodstock, belonging to the technical field of aquaculture. Background technique

[0002] The existing broodstock breeding adopts outdoor earthen ponds. The quality of broodstock breeding largely depends on the natural environment. It is difficult to achieve the controllability of breeding, which is not conducive to the cultivation of healthy and high-quality seed fish. Injured and dying, under the condition that the wild resources of Yangtze saury are extremely endangered, this method of parent fish breeding and artificial reproduction is not conducive to the sustainable development of Yangtze saury. Broodstock can still survive after artificial breeding and is used for artificial breeding in the next cycle. Therefore, it is necessary to study the ecological factory breeding technology of swordfish broodstock to avoid the problems and shortcomings of the prior art. Contents of...
